Finite Element Analysis on Dynamic Response of Bridge Structures under Moving Loads with Uniform Speed

Wen Zhang, De Can Yang

Abstract

The dynamic response of simple supported beam under the moving load is analyzed. The finite element analysis software MIDAS is used to simulate the process of when the uniform constant force moving through the simply supported beam. The first 5 natural frequencies of simply supported beam are obtained with the modal analysis and compared with the analytical solution. The feasibility of the finite element method is verified.
